FYI. During "make modules", I get this error:

make[2]: Entering directory `/usr/src/linux-2.2.11-ac3/drivers/sound'
...
maestro.c: In function `ac97_mixer_ioctl':
maestro.c:1554: `s' undeclared (first use this function)
maestro.c:1554: (Each undeclared identifier is reported only once
maestro.c:1554: for each function it appears in.)
make[2]: *** [maestro.o] Error 1

There are 4 instances of code of the form

spin_lock_irqsave(&s->lock, flags);
val = card->mix.recmask_io(card,1,0);
spin_unlock_irqrestore(&s->lock, flags);

with no `s' in sight. Just to make it compile (I don't actually use
this module; having it enabled for compilation was evidently a mousing
error in "make xconfig"), I added a "struct ess_state *s;" at the top
of the function and "s = &card->channels[0];".
